java 关于JTable大小的问题

import javax.swing.table.*;
import java.awt.*;
import javax.swing.*;

class TeleQury extends JFrame
{
Button b = new Button();
TextField tf;
Object[][]cells=
{
{"","","","","","",""},
};
String[] columns={"用户名","手机号","余额","市话费","长途费","漫游费","网费"};
JTable t;
JScrollPane scroll;
public TeleQury()
{
Frame f = new Frame();
f.setSize(600,520);
f.setTitle("手机信息查询");
f.setBackground(Color.lightGray);
f.setResizable(false);

Panel p = new Panel();
Panel p1 = new Panel();
Panel p2 = new Panel();
t=new JTable(cells,columns);
t.setAutoResizeMode(t.AUTO_RESIZE_OFF);
t.setCellSelectionEnabled(false);
p1.add(new JScrollPane(t));
b.setLabel("查询");
p2.add(new Label("手机号"));
tf = new TextField(13);
p2.add(tf);
p2.add(b);
p.add(p1);
p.add(p2);
f.add(p);
f.setVisible(true);

}
public static void main(String args[])
{

new TeleQury();
}
}
高手们帮我看看如何改正JTable的属性，使Table不要显示那么大，
我只要一行数据。

不知道这个是不是你要的效果
import javax.swing.table.*;
import java.awt.*;
import javax.swing.*;

class TeleQury extends JFrame
{
Button b = new Button();
TextField tf;
Object[][]cells=
{
{"","","","","","",""},
};
String[] columns={"用户名","手机号","余额","市话费","长途费","漫游费","网费"};
JTable t;
JScrollPane scroll=new JScrollPane();
public TeleQury()
{
Frame f = new Frame();
f.setSize(600,520);
f.setTitle("手机信息查询");
f.setBackground(Color.lightGray);
f.setResizable(false);

Panel p = new Panel();
Panel p1 = new Panel();
Panel p2 = new Panel();
t=new JTable(cells,columns);
t.setAutoResizeMode(t.AUTO_RESIZE_OFF);
t.setCellSelectionEnabled(false);
p1.setLayout(null);
scroll.getViewport().add(t);
scroll.setBounds(10,10,310,50);
p1.add(scroll);
p1.setBounds(10,10,320,60);
b.setLabel("查询");
p2.add(new Label("手机号"));
tf = new TextField(13);
p2.add(tf);
p2.add(b);
p.add(p1);
p.add(p2);
f.add(p);
f.setVisible(true);
}
public static void main(String args[])
{
new TeleQury();
}
}

用JTable.setModel方法重新载入TABLEMODEL，具体实现查看JDK文档
